Gemstone Dispersion Test

[Lights_and_Shadows]

Hey there

Loving the new site, excellent work

Made a small gemstone test for the new LuxCore dispersion properties, hope it may prove useful. No bugs appeared during rendering and yes, this was an old 1.6 port that I copied over and rehashed. Some may recognize the scene itself, who knows.

I want to give a big shout-out to the current development team, excellent job so far bringing this back and already vastly improving it from where it was wonder what else is in store and I hope us fellow artists can help in any way.

Cheers

Here's a citrine for good measure

Quite a beauty, I like the warm tone.

And rendered extremely quickly too, granted I only had 2.5k samples set up for the condition. Only took around 40 minutes to render it out with both eye and light depth set to 500 as well. Significant leap forward from having to use the classic version with dispersion, and looks honestly better overall.

I'll have many more cuts modeled out in the near future so this will be on-going for a bit.

Hope you don't mind, felt it was better to add here than start a new thread...

Here's a test I did, one diamond with dispersion and the other without.

Was away for a night, so let it render to 30k samples!!

I don't mind at all, feel free

And very nice o.o Considering adding more lights to my scene to lighten it up a bit, too many dark areas + glare for my liking in my renders. Seems you have a good arrangement going, well worth the wait

It may be worth try to use a Gaussian pixel filter instead of the default to avoid the very small black frame around the very strong highlights

It is a classic problem of some pixel filter.

More topaz in an oval backgammon cut:

I'll reconsider my previous statement on my lighting, looks rather well from this angle. 5K samples isn't enough though, only took about 1h 15min total for it.

keep posting love gemstones.. I wonder how it would look to render a pirates treasure chest full off gemstones

Now for an amethyst to join the ranks

Not sure about the blue portions, quite possibly just a modeling miscalculation on my part; I am remaking the cuts by hand so naturally, human error is expected. Started modeling from the outside going inwards, and been getting better results from it. Might need to rework some of the cuts I have currently.
